Theoptical photographing lens assembly has a total of five lens elementswith refractive power.

The first lens element can have positive refractive power, anobject-side surface being convex in a paraxial region thereof and animage-side surface being concave in a paraxial region thereof.Therefore, it is favorable for properly adjusting the positiverefractive power so as to reduce the astigmatism and the total tracklength of the optical photographing lens assembly.

The second lens element has positive refractive power, so that it isfavorable for balancing the distribution of the positive refractivepower so as to avoid overloading the positive refractive power on onesingle lens element resulting in excessive aberration.

The third lens element with positive refractive power can have anobject-side surface being convex in a paraxial region thereof and has animage-side surface being concave in a paraxial region thereof.Therefore, it is favorable for the light convergence ability shiftingtowards the image plane of the optical photographing lens assembly withthe positive refractive power of the second lens element so as to keepthe optical photographing lens assembly compact. It is also favorablefor obtaining a wider viewing angle. Moreover, the surface design of thethird lens element is favorable for correcting the astigmatism andreducing the photosensitivity.

The fourth lens element can have positive refractive power, anobject-side surface being concave in a paraxial region thereof and animage-side surface being convex in a paraxial region thereof. Therefore,it is favorable for further correcting the astigmatism and sphericalaberration.

The fifth lens element can have negative refractive power and has animage-side surface being concave in a paraxial region thereof.Therefore, the principal point can be positioned away from the imageplane of the optical photographing lens assembly so as to reduce theback focal length for keeping a compact size. Furthermore, at least oneof the object-side surface and the image-side surface of the fifth lenselement has at least one inflection point, so that it is favorable forcorrecting aberration of the off-axis.

When an axial distance between the object-side surface of the first lenselement and the image plane is TL, and a maximum image height of theoptical photographing lens assembly (half of a diagonal length of aneffective photosensitive area of an image sensor) is ImgH, the followingcondition is satisfied: 0.8<TL/ImgH<2.5. Therefore, it is favorable forreducing the total track length of the optical photographing lensassembly so as to keep a compact size.

When an Abbe number of the fourth lens element is V4, and an Abbe numberof the fifth lens element is V5, the following condition is satisfied:0.2<V5/V4<0.5. Therefore, it is favorable for further correcting thechromatic aberration of the optical photographing lens assembly.

When a focal length of the optical photographing lens assembly is f, afocal length of the first lens element is f1, a focal length of thesecond lens element is f2, a focal length of the third lens element isf3, a focal length of the fourth lens element is f4, and a focal lengthof the fifth lens element is f5, the following condition is satisfied:0<(|f/f1|+|f/f2|+|f/f3|)/(|f/f4|+|f/f5|)<0.6. Therefore, it is favorablefor reducing the total track length of the optical photographing lensassembly so as to keep a compact size thereof and reduce itsphotosensitivity.

The aforementioned optical photographing lens assembly further includesa stop, such as an aperture stop, wherein an axial distance between thestop and the image-side surface of the fifth lens element is SD, and anaxial distance between the object-side surface of the first lens elementand the image-side surface of the fifth lens element is TD, thefollowing condition is satisfied: 0.8<SD/TD<1.1. Therefore, it isfavorable for making a balance between obtaining the telecentricity andthe wide viewing angle.

When the focal length of the optical photographing lens assembly is f,and a curvature radius of the image-side surface of the third lenselement is R6, the following condition is satisfied: 0<f/R6<2.0.Therefore, it is favorable for correcting astigmatism of the opticalphotographing lens assembly.

When an axial distance between the second lens element and the thirdlens element is T23, an axial distance between the third lens elementand the fourth lens element is T34, and an axial distance between thefourth lens element and the fifth lens element is T45, the followingcondition is satisfied: 0<(T23+T45)/T34<1.0. Therefore, it is favorablefor properly adjusting the axial distance between every lens elements soas to reduce the total track length for keeping the opticalphotographing lens assembly compact. Preferably, the following conditionis satisfied: 0<(T23+T45)/T34<0.75.

When half of a maximal field of view of the optical photographing lensassembly is HFOV, and the following condition is satisfied:0.80<1/tan(HFOV)<1.40. Therefore, it is favorable for enlarging thefield of view so as to obtain a larger image scene.

When the focal length of the second lens element is f2, and the focallength of the third lens element is f3, the following condition issatisfied: 0<f2/f3<10. Therefore, it is favorable for the lightconvergence ability shifting towards the image plane of the opticalphotographing lens assembly so as to keep the optical photographing lensassembly compact and obtain a wider viewing angle.

According to the optical photographing lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the optical photographing lensassembly may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than spherical surface so as to have more controllablevariables for eliminating the aberration thereof, and to furtherdecrease the required number of the lens elements. Therefore, the totaltrack length of the optical photographing lens assembly can also bereduced.

According to the optical photographing lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to the opticalaxis, and the off-axis region refers to the region of the surface wherelight rays travel away from the optical axis. Particularly, when thelens element has a convex surface, it indicates that the surface isconvex in the paraxial region thereof; when the lens element has aconcave surface, it indicates that the surface is concave in theparaxial region thereof.

According to the optical photographing lens assembly of the presentdisclosure, the optical photographing lens assembly can include at leastone stop, such as an aperture stop, a glare stop or a field stop. Saidglare stop or said field stop is for eliminating the stray light andthereby improving the image resolution thereof.

According to the optical photographing lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between an imaged object and thefirst lens element can provide a longer distance between an exit pupilof the optical photographing lens assembly and the image plane andthereby improves the image-sensing efficiency of an image sensor. Amiddle stop disposed between the first lens element and the image planeis favorable for enlarging the field of view of the opticalphotographing lens assembly and thereby provides a wider field of viewfor the same.
